《水工建筑物》介绍了土坝斜墙与保护层稳定计算的数解法,有的水电设计部门用此法编制了电算程序。我们曾用这种方法验算斜墙和斜心墙坝的稳定,发现教材的某些观点有必要进一步讨论。《水工建筑物》教材有关内容如下; 如图(1)假定折线滑动面LBGD.抗滑力和滑动力之比是斜墙连同保护层沿拟定滑面滑动的稳定安全系数。 Hydraulic Structures describes the numerical solution of the stability calculation of inclined walls and protective layers of earth dams. Some hydropower design departments have compiled computer programs by this method. We have used this method to verify the stability of sloped and inclined wall dams and found that some of the views of textbooks need to be further discussed. As shown in Figure 1, the line-sliding surface LBGD is assumed to be the ratio of anti-sliding force to sliding force, which is the stable safety factor of the sloping wall along with the protective layer sliding along the proposed sliding surface.
